  • Patent number: 7872710
    Abstract: Disclosed is an LCD device and a method for fabricating the same, capable of preventing defects derived from a defective UV-curing of a sealant while employing one-drop fill technology. The LCD device includes an array substrate having a metal signal line, a thin film transistor and a pixel electrode, a color filter substrate having a light shielding pattern and a color filter, a sealant interposed between the substrates and cured in order to fixedly combine the array substrate with the color filter substrate, and a liquid crystal layer interposed between the array substrate and the color filter substrate through one-drop fill technology. The shielding pattern is made of resin including a transparent heat-sensitive pigment, in which a color of the heat-sensitive pigment is changed to black through a heat-sensitive reaction and UV light passes through the heat-sensitive pigment.
